SELF-CLOSING HINGE.

To all whom it may concern:

Be it known that I, GEORGE A. DATSCHEG, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Self-Closing Hinge, of which the following is a specification.

My invention relates to a new and useful hinge for gates, doors, etc. and consists in providing means whereby the said gates, doors, etcA are automatically closed and held in the set position, and wherein I provide a small bearing surface and' a roller bearing for ease of operation, as will be evident.

It further consists of novel details of construction, all as will be hereinafter fully set forth.

Figure l represents a perspective view of an upper portion of the hinge. Fig. 2 represents a perspective view of the lower portion ol` the hinge in separate position. Fig. 3 represents a sectional view of the parts when connected. Fig. 4 represents a sectional view showing the parts in different position from that shown in Fig. 3. liig. 5 represents a perspective view of the upper portion of the pintle, showing the groove therein. F ig. (i represents an elevation showing the hinges as applied to a gate.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings: I have found in practice, that in the hinges now in use, it is of advantage to have a self-closing hinge and in addition to provide a bearing 'surface for the movable parts, which is small in extent and which rests upon roller bearings in order that the hinge may work easily and whereby but little ierce is required to open the gate.

In the drawing I have shown a construction tor carrying out this invention, but it will be evident that other instrumentalities may be employed than those shown, which will accomplish the same results, and I do not, therefore, desire to be limited in. every instance, to the exact construction herein shown and described.

l designates a fence having the posts 2, although it will be evident that but a single post may be employed, it desired, where a` single gate is used.

In Fig. G I have shown two gates, either of which can be opened and will close automatically, and will describe but one oi these, as any number may be einployed.

3 designates a bracket which is secured in any desired manner, inthe present instance, by means of bolts passing through the openings 4, to the post 2, or other suitable support. In connection with and forming part of said bracket, is a pintle 5, having a groove G in its upper portion, and the upper face' of which is beveled or inclined at 7. Adapted to be situated in said groove Specification of Letters Patent.

and projecting slightly above the plane ot the beveled surface 7 are the two roller bearings S and 9. A It will be noticed that the face opening oi the groove is smaller than the diameter of the roller bearings and that therefore these bearings while permitted to rotate are prevented irom moving from their position, the advantages oi which are evident.

IQ designates a socket which is adapted to lit said pintle 5 and rotate around the same, as will be hereinafter described, said socket having secured thereto a pin 1I which, in the present instance, is secured by the screw l2, although any desired means for securing the same may be employedA The lower face of said pin is provided with the inclined faces or tracks I3 which are formed by having a recessed portion 14 therebetween, it being noted that said tracks are adapted to rest upon the roller bearings 8 and 9 when the parts are in position, as understood from the Figs. 3 and 4.

I5 designates a standard suitably connected to the pin and around which is situated a sleeve 1G which is provided with a socket 17 adapted to receivel a rail I8 of the gate, a lug I9 being connected. with said socket and sleeve and is adapted to have connected therewith, a portion 20 forming a part oi the gate. The upper portion of the standard I5, when the parts are in position, moves in a suitable bracket 2l connected with the post or support 2.

The operation of the parts will be readily understood. When the sleeve l0 is rotated upon the pintle 5, depending upon which direction the sleeve is rotated, one or other of the tracks I3 will move on the roller bearings 8 or 9 so that the sleeve l0 and its connected parts will be elevated, this being easily accomplished by reason of` the narrow extent of the bearing surface 13 and by reason oi the roller bearings S and 9, the advantages of which are evident. By this means it will be seen that when the gate 22, which is carried by the hinge, is moved in either direction, it will be slightly elevated and when released, the same will be immediately closed and remain in this position until again moved.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is z- 1. In a device of the character described, a pintle rigidly supported, an inclined face on said pintle having a groove extending' across the same, roller bearings in said groove, said groove being smaller' than the diameter of said roller bearings, a socket encircling said pintle, an inclined track carried by said socket bearing on said rollers, whereby when the parts are turned the socket will be elevated on said pintleA y 2. In a device of the character described, a pintle rigidly supported, an inclined face on said pintle having a groove extending across its surface, roller bearings rotatably mounted in said groove projecting slightly beyond the inclined face and prevented from lateral dismovable on said pintlc, inclined tracks carried by said l() placemenha socket encircling said pintle, an inclined track socket bearing on said roller, and a socket connected with carried by said socket bearing on said rollers whereby when said first mentioned socket and adapted to receive a snitthe pau-ts are turned, the socket will be elevated 0n said able portion of a gate.
